- DESCRIPTION
-
-
- Awk Traps
- C/C++ Traps
- Sed Traps
- Shell Traps
- Perl Traps
- Perl4 to Perl5 Traps
- Discontinuance, Deprecation, and BugFix traps, Parsing Traps, Numerical Traps, General data type traps, Context Traps - scalar, list contexts, Precedence Traps, General Regular Expression Traps using s///, etc, Subroutine, Signal, Sorting Traps, OS Traps, DBM Traps, Unclassified Traps
- Discontinuance, Deprecation, and BugFix traps
- Symbols starting with ``_'' no longer forced into main, Double-colon valid package separator in variable name, 2nd and 3rd args to "splice()" are now in scalar context, Can't do "goto" into a block that is optimized away, Can't use whitespace as variable name or quote delimiter, "while/if BLOCK BLOCK" gone, "**" binds tighter than unary minus, "foreach" changed when iterating over a list, "split" with no args behavior changed, -e behavior fixed, "push" returns number of elements in resulting list, Some error messages differ, "split()" honors subroutine args, Bugs removed
- Parsing Traps
- Space between . and = triggers syntax error, Better parsing in perl 5, Function parsing, String interpolation of $#array differs, Perl guesses on "map", "grep" followed by "{" if it starts BLOCK or hash ref
- Numerical Traps
- Formatted output and significant digits, Auto-increment operator over signed int limit deleted, Assignment of return values from numeric equality tests doesn't work, Bitwise string ops
- General data type traps
- Negative array subscripts now count from the end of array, Setting $#array lower now discards array elements, Hashes get defined before use, Glob assignment from localized variable to variable, Assigning "undef" to glob, Changes in unary negation (of strings), Modifying of constants prohibited, "defined $var" behavior changed, Variable Suicide
- Context Traps - scalar, list contexts
- Elements of argument lists for formats evaluated in list context, "caller()" returns false value in scalar context if no caller present, Comma operator in scalar context gives scalar context to args, "sprintf()" prototyped as "($;@)"
- Precedence Traps
- LHS vs. RHS of any assignment operator, Semantic errors introduced due to precedence, Precedence of assignment operators same as the precedence of assignment, "open" requires parentheses around filehandle, $: precedence over $:: gone, Precedence of file test operators documented, "keys", "each", "values" are regular named unary operators
- General Regular Expression Traps using s///, etc.
- "s'$lhs'$rhs'" interpolates on either side, "m//g" attaches its state to the searched string, "m//o" used within an anonymous sub, $+ isn't set to whole match, Substitution now returns null string if it fails, "s`lhs`rhs`" is now a normal substitution, Stricter parsing of variables in regular expressions, "m?x?" matches only once, Failed matches don't reset the match variables
- Subroutine, Signal, Sorting Traps
- Barewords that used to look like strings look like subroutine calls, Reverse is no longer allowed as the name of a sort subroutine, "warn()" won't let you specify a filehandle
- OS Traps
- SysV resets signal handler correctly, SysV "seek()" appends correctly
- Interpolation Traps
- "@" always interpolates an array in double-quotish strings, Double-quoted strings may no longer end with an unescaped $, Arbitrary expressions are evaluated inside braces within double quotes, $$x now tries to dereference $x, Creation of hashes on the fly with "eval "EXPR"" requires protection, Bugs in earlier perl versions, Array and hash brackets during interpolation, Interpolation of "\$$foo{bar}", "qq()" string passed to "eval" will not find string terminator
- DBM Traps
- Perl5 must have been linked with same dbm/ndbm as the default for "dbmopen()", DBM exceeding limit on the key/value size will cause perl5 to exit immediately
- Unclassified Traps
- "require"/"do" trap using returned value, "split" on empty string with LIMIT specified

perluniintro - Perl Unicode introduction
perlunicode - Unicode support in Perl
- DESCRIPTION
-
-
- Important Caveats
- Input and Output Layers, Regular Expressions, "use utf8" still needed to enable UTF-8/UTF-EBCDIC in scripts, BOM-marked scripts and UTF-16 scripts autodetected, "use encoding" needed to upgrade non-Latin-1 byte strings
- Byte and Character Semantics
- Effects of Character Semantics
- Unicode Character Properties
- General Category, Bidirectional Character Types, Scripts, Extended property classes, Use of ``Is'' Prefix, Blocks
- User-Defined Character Properties
- User-Defined Case Mappings
- Character Encodings for Input and Output
- Unicode Regular Expression Support Level
- Unicode Encodings
- Security Implications of Unicode
- Unicode in Perl on EBCDIC
- Locales
- When Unicode Does Not Happen

perlunifaq - Perl Unicode FAQ
- Q and A
-
-
- perlunitut isn't really a Unicode tutorial, is it?
- What character encodings does Perl support?
- Which version of perl should I use?
- What about binary data, like images?
- When should I decode or encode?
- What if I don't decode?
- What if I don't encode?
- Is there a way to automatically decode or encode?
- What if I don't know which encoding was used?
- Can I use Unicode in my Perl sources?
- Data::Dumper doesn't restore the UTF8 flag; is it broken?
- Why do regex character classes sometimes match only in the ASCII range?
- Why do some characters not uppercase or lowercase correctly?
- How can I determine if a string is a text string or a binary string?
- How do I convert from encoding FOO to encoding BAR?
- What are decode_utf8 and encode_utf8?
- What is a wide character?

- Step-by-step: Preparing the ground
- Look around, Check it's new, Discuss the need, Choose a name, Check again
- Step-by-step: Making the module
- Start with module-starter or h2xs, Use strict and warnings, Use Carp, Use Exporter - wisely!, Use plain old documentation, Write tests, Write the README
- Step-by-step: Distributing your module
- Get a CPAN user ID, "perl Makefile.PL; make test; make dist", Upload the tarball, Announce to the modules list, Announce to clpa, Fix bugs!

-
- No Parameters, Nothing returned
- Passing Parameters
- Returning a Scalar
- Returning a list of values

- Using G_KEEPERR
- Using call_sv
- Using call_argv
- Using call_method
- Using GIMME_V
- Using Perl to dispose of temporaries
- Strategies for storing Callback Context Information
- 1. Ignore the problem - Allow only 1 callback, 2. Create a sequence of callbacks - hard wired limit, 3. Use a parameter to map to the Perl callback

perlhack - How to hack at the Perl internals
- DESCRIPTION
-
Does concept match the general goals of Perl?, Where is the
implementation?, Backwards compatibility, Could it be a module instead?, Is
the feature generic enough?, Does it potentially introduce new bugs?, Does
it preclude other desirable features?, Is the implementation robust?, Is
the implementation generic enough to be portable?, Is the implementation
tested?, Is there enough documentation?, Is there another way to do it?,
Does it create too much work?, Patches speak louder than words
